comnmnn ROLLER m ICE SKATE.

Specification of Letters Patent.- Pa,teni;ed Oct. 26, 1909.

Application flled ll'anuary 16, 1909. Serial No. 472,730.

To all whom it may concern:

Be it known that I, JOHN A. NOLAN, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State of Illinois,-have invented certain new and useful Improvements in a Combined Roller and Ice tSkate, of which the following is a specifica- 1on.

This invention relates to improvements in that type of skates which can be employed either as roller-skates for use on smooth wooden floors or other hard surfaces, or for use on ice, and it consists in certain peculiar-- ities of the construction, novel arrangement, and operation of the various parts thereof, as will be hereinafter more fully set forth and specifically claimed.

The principal object ofthe invention is to provide a skate which shall be simple and inexpensive in construction, strong, durable and effective in operation, and so made that when used as a roller-skate the rollers thereof mag be readily removed and the other parts thereof secured together in such a man-,

ner as .to provide a skate adapted for use on ice, and vice versa.

A further object of the invention is "to provide means whereby when the skate is used as a roller one the rollers thereof will be held with respect toone another so that the lower extremities of their peripheries will describe an arc of a circle with respect to one another, to the end that the innermost roller may act as a .pivot on which the skate may be sharply or abruptly turned.

A further object of the invention is to pro vide means for rigidly holding the skatey scription and explanation.

In order to enable others skilled in the art to which my invention pertains, to make and. use the same, I will now proceed to describe it, referring to the accompanying drawing,

in which 4 Figure 1 is a view in side-elevation of a skate embodying one form of the invention,

showing the rollers-thereof in position on the skate-blades and ready for use; Fig. 2 is a. cross-sectional view taken on line 22 of Fig. 1 looking in thedirection indicated by the arrows, showing the position the parts will occupy when used as a roller-skate; Fig. 3 is a similar view taken on the same line, showing the position the parts will occupy when ready for use'as an ice-skate; Fig. 4 is a fragmental view partly in section and partly in elevation, showing one form, or arrangement of anti-friction ball bearings for the axles of the rollers; Fig. 5 is a similar view showing a modified form or arrangement of the ball bearings for the rollers; and Fig. 6 is a view partly in cross-section and partly in elevation of another modified form of the skate.

Like numerals of reference,refer to corresponding parts throughout the different views of the drawing.

The reference numeral 10 designates the.

.with any suitable means for securing it to the shoe of the user, but in the present instance is shown as being provided with clamps 11 operated by a lever 12 in the wellknown way. As the invention does not relate to the means for. securing the foot-plate to the shoe of the user, and as any desired means for this purpose may be employed, a detail description ofsuch securing means 1s deemed unnecessary and will not be herein given. Depending from the lower surface of the foot-plate at a slight distance on each side of the longitudinal center or axis thereof are a number of lugs 13 which are formed with longitudinally extended openings, and

-are arranged in pairs as shown in Fig. 1 of the drawlng. These lugs may be made integrally with the foot-plate or may be other wise. secured on its lower surface, and are for the purpose of ivotally s'ecuringthe skate-blades 14 to t e foot-plate, each of which blades is provided with a number of" vertical extensions 15 each of which has at its upper end a longitudinally extended tubular portion 16 to fit between, the lugs 13 of each pairthereof, and said tubular portions are secured to the lu pintles 17.?extended through t e openings of the lugs and the openings of the tubular parts 16, thus pivotally securing or hinging the blades 14 to the foot-pl e. When thus by means of' secured in place it is apparent that the blades 14, as well as their extensions 15, will be held 1n parallelism with one another at a sufficient distance apart to permit of the reception and operation therebetween of the rollers 18, which may be made of any suitable size and material and may be of any desired number, but preferably of an odd number.

skate-bla'des'are in the positions shown in Figs. 1 and 2 of the drawing and equipped with the rollers. Each of the parts 16 of the extensions 15 is provided on its inner surface with a beveled lug 23 to contact with the lower surface of the foot-plate when the blades and their extensions are in the positions-shown in Fig. 3 of the drawing and when the skate has its parts adapted or arranged for use as an ice-skate. The lower portion of each of the blades 14 is outwardly deflected throughout its entire length as at 14 so that when the rollers 18 are removed and the blades are brou ht together at their lower portions their a jacent surfaces will contact with one another thl'OllgllOllt their entire lengths, in which positions they will beheld by means of bolts 24 passed through suitable openings 25 in the extensions 15 and nuts 26 on the end of said bolts, all of which w ll be clearly understood by reference to F 1g. 3 of the drawin In orderto more rigidly secure the bla es 14 in parallelism w1th one anotherwhen the rollers 18 are employed therebetween a collar 27 is located on each of the bolts 24 between the extens1ons 15,. as is clearly shown in Fig. 2 of the drawing.

Instead of placing the balls 20 within the open1ngs'19 of the skate-blades they maysomet mes beheld around the axles 21 by means of suitable cups 28 secured to the sides of the wheels, thus permittingthem to be removed therewith, as will be readily understood by reference to Fig. 5 of the drawin In Flg 6 is shown a modification in the construction of the skate, which consists in rigidly securing-the extensions 15 of one of the skate-blades 14 to the foot-plate 10 instead of pivotally securing the extensions 15.

on both of said blades as in the other construction, in which modified form it .will be seen that the pivoted blade will assume the pos1t1on shown by dotted lines in-Fi 6 when the rollers 18 have been removed so that the skate may be adapted forice, and

figure of the drawing that the lower edges of the blades 14 and 14 will be located a little to one side of a vertical line through the middle of the foot-plate, which latter loca-' tion will be so slight that it will not interfere with the operation of the skate.- By hinging one of theblades only to the foot-plate 10 as shown. in Fig. 6 it is apparent that by removing the bolts 24 the hinged blade may be moved outwardly, and thus permit the rollers and their axles to be easily removed, and especially is this so when the ball bear- Fig. 5, instead of to the blades 14, as shown in Fig. 4 of the drawing.

ings are secured vto the rollers, as shown in From the foregoing and by reference to I the drawing it will be seenand readily understood that by employing an odd'number of rollers on the blades 14 and arranging them so that the lower parts of their peripheries will describe an arc with respect to one another the innermost roller will act as a pivot on which the skate may be sharply turned, which could not be performed were all of the rollers located in a straight line at their lower portions. ing the lower edges of each 0 the skateblades as at 29 it is apparent that when said blades arebrought into cbntact and secured in such position by means of the bolts 24 and nuts 26 the hollow ground effect or shape will be produced, which is often very desirable. It will be understood that the invention is susceptible of considerable modification without departin from the principles and spirit thereof, an for this reason I do not desire to be limited to the exact construction and arrangement of the parts herein shown and set forth.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters-Patent, is-- 1. In a skate the combination with a footplate, of a pair of spaced apart skate-blades adjustably secured to the lower surface By sli 'htly bevel-.

thereof, and a series of rollers journaled between said blades and adapted to be detached therefrom.

3. In a skate the combination with a footplate, of a pair of spaced apart skate-blades secured to the lower surface thereof in parallelism with one another, means to ad ustably secure at least one of said blades to the foot-plate, a series of rollers journale d between the blades, and means to secure the blades together.

4. In a skate the combination with a footthrough the openings of the lugs and apertured portions of said extensions, and means to securesaid extensions together.

5. In a skate the combination with a footplate havin on its lower surface a series of ,longitudina 1y apertured lugs arranged in pairs on each side of the longitudinal axis Y skate-blades each of the plate, of a pair of having vertical extensions provided at their upper ends with apertured portions to fit between the lugs of each pair, pintlesextended through the openings of thelugs and apertured portions of said extensions, 'a series of rollers detachably journaled between the blades, and means for securing the said extensions together. 1

6. In a skate the combination with a footplate, of a pair of skate-blades hinged to the lower surface thereof at a distance apart and in parallelism with one another, and means to secure said blades together.

7. In a skate\the combination with a footlat,

apertured portions to fit between the lugs of each pair, pintles extended plate, tical extensions hinged to the lower surface of the foot-plate in parallelism with one anof a pair of skate-blades hinged to the lower surface thereof at a distance apart and in parallelism with one another, a series of rollers detachably journaled between the blades, and means to secure said bladestogether.

8. In a skate the combination with a footof a pair of skate blades having verother and at a 'slight distance apart, each of said extensions havin on its upper portion an outwardly exten ed lug, a series of rollers journaled between the blades, and means to secure said extensions together.

9. In a skate the combination with a footplate, of a pair of skate-blades having ver tical extensions hinged to the lower surface of the foot-plate in parallelism with one another and at a slight distance apart, each of said extensions having on its upper portion an inwardly extended lug, and means to secure said extensions together.
